An Introduction to Sequential Monte Carlo

open access: yes, 2020
Particle filters are about 25 years old. Initially confined to the so-called “filtering problem” (the sequential analysis of state-space models), they are now routinely applied to a large variety of sequential and non-sequential tasks and have evolved to the broader Sequential Monte Carlo (SMC) framework.

Efficient Monte Carlo filtering for discretely observed jumping processes [PDF]

open access: yes, 2007
This paper addresses a tracking problem in which the unobserved process is characterised by a collection of random jump times and associated random parameters.

Monte Carlo filtering of piecewise deterministic processes [PDF]

open access: yes, 2011
We present efficient Monte Carlo algorithms for performing Bayesian inference in a broad class of models: those in which the distributions of interest may be represented by time marginals of continuous-time jump processes conditional on a realisation of

Sequential Monte Carlo with model tempering

open access: yesStudies in Nonlinear Dynamics & Econometrics, 2023
Abstract Modern macroeconometrics often relies on time series models for which it is time-consuming to evaluate the likelihood function. We demonstrate how Bayesian computations for such models can be drastically accelerated by reweighting and mutating posterior draws from an approximating model that allows for fast likelihood ...

Multilevel sequential Monte Carlo samplers [PDF]

open access: yesStochastic Processes and their Applications, 2017
In this article we consider the approximation of expectations w.r.t. probability distributions associated to the solution of partial differential equations (PDEs); this scenario appears routinely in Bayesian inverse problems. In practice, one often has to solve the associated PDE numerically, using, for instance finite element methods and leading to a ...

Bayesian model selection for multilevel models using integrated likelihoods.

open access: yesPLoS ONE, 2023
Multilevel linear models allow flexible statistical modelling of complex data with different levels of stratification. Identifying the most appropriate model from the large set of possible candidates is a challenging problem. In the Bayesian setting, the

Variational Sequential Monte Carlo

open access: yes, 2017
Many recent advances in large scale probabilistic inference rely on variational methods. The success of variational approaches depends on (i) formulating a flexible parametric family of distributions, and (ii) optimizing the parameters to find the member of this family that most closely approximates the exact posterior.
